ADV7403KSTZ-140

Overview

The ADV7403KSTZ-140 is a 12-bit integrated multiformat SDTV/HDTV video decoder and RGB graphics digitizer. It features four Noise Shaped Video (NSV) analog-to-digital converters sampling up to 140 MHz, supporting NTSC, PAL, and SECAM standards. The device includes a multiplexer with 12 analog input channels, internal antialias filters, and a 24-bit digital input port for DVI/HDMI receiver data. It provides 12-bit 4:4:4 and 10-/8-bit 4:2:2 DDR pixel output interfaces, any-to-any 3x3 color-space conversion, and operates within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Supports high-speed 140 MHz sampling for advanced HDTV and graphics processing
• Integrates a 12-channel analog input multiplexer with SCART fast blank support
• Includes a 24-bit digital input port compatible with DVI and HDMI receiver ICs
• Features any-to-any 3x3 color-space conversion matrix for flexible signal processing

Applications

• LCD/DLP rear projection HDTVs
• PDP HDTVs
• CRT HDTVs
• HDTV set-top boxes with PVR
• Hard-disk-based video recorders

Procurement Notes

Verify the specific KSTZ-140 suffix indicates the 140 MHz speed grade variant when sourcing. Confirm that the operating temperature range aligns with your system requirements, as this specific grade supports the full industrial range from −40°C to +85°C. Ensure power supply voltages match the specified AVDD, DVDD, and DVDDIO levels during integration.

Selection Notes

Select this component for designs requiring simultaneous decoding of standard definition composite/S-video and high-definition component signals. The 140 MHz speed grade is necessary for digitizing RGB graphics up to SXGA resolutions at 75 Hz. Consider the integrated 12-channel mux if external switching components are to be minimized in the analog front end.

Part Context

This part belongs to the ADV7403 family of video decoders manufactured by Analog Devices. It serves as a bridge between legacy analog video sources and modern digital display processors. The KSTZ-140 designation specifically denotes the package type and the maximum clock speed capability compared to other variants in the series.

Replacement Considerations

The ADV7403BSTZ-110 is a confirmed substitute within the same family, offering identical functionality but limited to an 110 MHz sampling rate.
